 # Regression Wasm
 
-This repository will serve code compiled to Wasm to perform regression in the browser
+This repository serves a simple [web assembly](https://webassembly.org/) (wasm) application 
+to perform a regression, using data from a table in the browser, which can be loaded as a delimited file
+by the user. We use a simple [regression library](https://github.com/sajari/regression) to do
+the work.
 
-*under development*
+## About
+
+### Why?
+
+Web assembly can allow us to interact with compiled code directly in the browser,
+doing away with any need for a server. While I don't do a large amount of data analysis
+for my role proper, I realize that many researchers do, and so with this in mind, 
+I wanted to create a starting point for developers to interact with data in the browser.
+The minimum conditions for success meant:
+
+ 1. being able to load a delimited file into the browser
+ 2. having the file render as a table
+ 3. having the data be processed by a compiled wasm
+ 4. updating a plot based on output from 3.
+
+Thus, the application performs a simple regression based on loading data in the table,
+and then plotting the result. To make it fun, I added a cute gopher logo and used an xkcd
+plotting library for the result.
+
+### Customization
+
+The basics are here for a developer to create (some GoLang based) functions to
+perform data analysis on an input file, and render back to the screen as a plot.
+If you need any help, or want to request a custom tool, please don't hesitate to
+[open up an issue](https://www.github.com/vsoch/regression-wasm/issues).
+
+## Development
+
+### Local
+
+If you are comfortable with GoLang, and have installed [emscripten](https://emscripten.org), 
+you can clone the repository into your $GOPATH under the github folder:
+
+```bash
+$ mkdir -p $GOPATH/src.github.com/vsoch
+$ cd $GOPATH/src.github.com/vsoch
+$ git clone https://www.github.com/vsoch/regression-wasm
+```
+
+And then build the wasm.
+
+```bash
+$ make
+```
+
+And cd into the "docs" folder and start a server to see the result.
+
+```bash
+$ cd docs
+$ python -m http.server 9999
+```
+
+Open the browser to http://localhost:9999
+
+
+## Docker
+
+If you don't want to install dependencies, just clone the repository, and
+build the Docker image:
+
+```bash
+$ docker build -t vanessa/regression-wasm .
+```
+
+It will install [emscripten](https://emscripten.org/docs/getting_started/FAQ.html),
+add the source code to the repository, and compile to wasm. You can then
+run the container and expose port 80 to see the compiled interface:
+
+```bash
+$ docker run -it --rm -p 80:80 vanessa/regression-wasm
+``` 
+
+Then you can proceed to use the interface.
